1992, Book chapter, Ecology and Management of Breeding Waterfowl
In this chapter we review the techniques used to measure two important parameters of waterfowl populations, size of breeding population and recruitment. If waterfowl are to be managed toward goals defined in terms of population sizes such as those in the recently signed North American Waterfowl Management Plan (U.S. Fish...
U.S. Geological Survey Library classification system
R. Scott Sasscer
1992, Bulletin 2010_1992
The U.S. Geological Survey library classification system has been designed for an earth science library. It is a tool for assigning classification numbers to earth science and allied pure science library materials in order to collect these materials into related subject groups on the library shelves and arrange them alphabetically...

Implications for faunal habitat related to altered macrophyte structure in regulated lakes in northern Minnesota
Douglas A. Wilcox, James E. Meeker
1992, Wetlands (12) 192-203
Water-level regulation has altered the plant species composition and thus the structure of nearshore aquatic macrophyte communities in two regulated lakes in northern Minnesota as compared with a nearby unregulated lake. Results of previous faunal studies in the regulated lakes were used as a basis for assessing the effects of...

A new device for collection of interstitial water from wetland sediments
Ned H. Euliss Jr., Ronald K. Barnes
1992, Wetlands Ecology and Management (1) 233-237
A sampler for collection of interstitial water from wetland sediments is described. It differs from other sampling devices because it does not have to be filled with solution to facilitate diffusion, it does not have to be removed from the wetland to collect samples, and it can be used to...

Breeding chronology of mottled ducks in a Texas coastal marsh
J. Barry Grand
1992, Journal of Field Ornithology (63) 195-202
The relationship between breeding chronology of Mottled Ducks (Anas fulvigula fulvigula) and wetland conditions at San Bernard National Wildlife Refuge was examined over a 3-yr period. Median nest initiation dates varied by as much as 68 d among years. Initiation occurred earlier in 1985 and 1987 versus 1986 (P <...
Intraspecific variation in egg shape among individual emperor geese
Margaret R. Petersen
1992, Journal of Field Ornithology (63) 344-354
Within-clutch variability in shape of 1743 eggs from 301 nests of Emperor Geese (Chen canagicus) laid over a 5-yr period was measured. Individual females laid similar shaped eggs in successive years, and eggs among clutches within females could not be distinguished. Cluster analysis correctly identified 69.9% of 136 known conspecific...
Sampling vadose-zone water for a volatile organic compound at Picatinny Arsenal, New Jersey
James A. Smith, H. Jean Cho, Peter R. Jaffe, Cecilia L. MacLeod, Susan A. Koehnlein
1992, Journal of Environmental Quality (21) 264-271
A new method of collecting samples of unsaturated-zone water for quantitative analysis for a volatile organic compound, trichloroethene (TCE), was compared to three other, previously described sampling methodologies in the laboratory and in the field. In the laboratory, prepared water samples containing TCE in a known concentration (20 µg/L) were...
Lake trout spawning habitat in the Six Fathom Bank-Yankee Reef lake trout sanctuary, Lake Huron
Thomas A. Edsall, Charles L. Brown, Gregory W. Kennedy, Thomas P. Poe
1992, Journal of Great Lakes Research (18) 70-90
Attempts to reestablish self-sustaining stocks of lake trout (Salvelinus namaycush) in the lower four Great Lakes, where the species was extinguished in the 1950s and 1960s, have been largely unsuccessful. To avoid many of the problems believed to be contributing to this failure, the fishery management community recently established several...

In this chapter, we discuss methods for conducting bioaccumulation bioassays with fish; the advantages and disadvantages of using fish rather than invertebrates; and problems associated with bioaccumulation testing, with a special emphasis on statistical treatment....

A hydrogen-oxidizing, Fe(III)-reducing microorganism from the Great Bay estuary, New Hampshire
F. Caccavo Jr., R.P. Blakemore, Derek R. Lovley
1992, Applied and Environmental Microbiology (58) 3211-3216
A dissimilatory Fe(III)- and Mn(IV)-reducing bacterium was isolated from bottom sediments of the Great Bay estuary, New Hampshire. The isolate was a facultatively anaerobic gram-negative rod which did not appear to fit into any previously described genus. It was temporarily designated strain BrY. BrY grew anaerobically in a defined medium...
Evaluation of methyl fluoride and dimethyl ether as inhibitors of aerobic methane oxidation
Ronald S. Oremland, Charles W. Culbertson
1992, Applied and Environmental Microbiology (58) 2983-2992
Methyl fluoride (MF) and dimethyl ether (DME) were effective inhibitors of aerobic methanotrophy in a variety of soils. MF and DME blocked consumption of CH4 as well as the oxidation of 14CH4 to 14CO2, but neither MF nor DME affected the oxidation of [14C]methanol or [14C]formate to 14CO2. Cooxidation of ethane and propane by methane-oxidizing...

A technique for the reduction of banding in Landsat Thematic Mapper Images
Dennis L. Helder, Bruce K. Quirk, Joy J. Hood
1992, Photogrammetric Engineering and Remote Sensing (58) 1425-1431
The radiometric difference between forward and reverse scans in Landsat thematic mapper (TM) images, referred to as "banding," can create problems when enhancing the image for interpretation or when performing quantitative studies. Recent research has led to the development of a method that reduces the banding in Landsat TM data...
Structural evolution of an arc-basin: The Gravina Belt in central southeastern Alaska
Peter J. Haeussler
1992, Tectonics (11) 1245-1265
The upper Middle Jurassic-Lower Cretaceous Gravina belt lies along the eastern margin of the Alexander terrane in southeastern Alaska. This group of turbidites and mafic to intermediate volcanic rocks was deformed during mid to Late Cretaceous time during the closing of a basin of unknown size between the Alexander terrane...

Roosting behavior of premigratory Dunlins (Calidris alpina)
Colleen M. Handel, Robert E. Gill Jr.
1992, The Auk (109) 57-72
We studied roosting behavior of Dunlins (Calidris alpina) during late summer along the coast of the Yukon-Kuskokwim Delta, Alaska, in relation to tidal cycle, time of day, time of season, and occurrence of predators. Within Angyoyaravak Bay, peak populations of 70,000-100,000 Dunlins occur each year. The major diurnal roost sites...
